U8 (DF0001082)

This model represents a noncoding RNA gene. Some ncRNA genes have transformed into, or become assimilated into transposons. Others occur in sufficient copy number that ab initio repeat finders may classify them as repetitive elements. This entry is used to correctly identify the gene and its pseudogenes and prevent misannotation.

U8 C/D box snoRNA gene / pseudogene


U8 snoRNA (small nucleolar RNA) is an unusual snoRNA that is involved in pre-rRNA cleavage rather than RNA methylation. While there is only a small number of U8 genes (perhaps only 1 copy), there are a couple of dozen pseudogenes in human.
